- Confidence votes 2.1K. The function of the capillaries is to distribute oxygen carried on the hemoglobin of the red cells to all the cells of the body. The blood also carries nutrients to all the cells of the body. Blood comes to the capillaries through the arteries, then is sent back to the heart via the veins.Capillaries are also the waste disposal system for the cells of the body.Water, carbon dioxide, and other wastes are uploaded to the blood to be disposed of in the kidneys, lungs and liver. Capillaries are an integral and essential component of your body's circulatory system. 2  Without these very small structures, your body wouldn't be able to bring blood to your 3  …. How Heart Disease Affect the Capillaries' Function The term heart disease concerns any disease that affects the heart and blood vessels.

Human Circulatory System Human Circulatory System. The human circulatory system functions to transport blood and oxygen from the lungs to the various tissues of the body. The heart pumps the blood throughout the body. The lymphatic system is an extension of the human circulatory system that includes cell-mediated and antibody-mediated immune systems. The components of the human circulatory system include the heart, blood, red and white blood cells, platelets, and the lymphatic system.

Circulatory System Capillaries are small, normally around 3-4µm, but some capillaries can be 30-40 µm in diameter. The largest capillaries are found in the liver. (capillar comes from the greek for hairlike). Capillaries connect arterioles to venules. They allow the exchange of nutrients and wastes between the blood and the tissue cells, together with the interstitital fluid. This exchange occurs by passive diffusion and by pinocytosis which means 'cell drinking'. Pinocytosis is used for proteins, and some lipids.

Understanding Capillary Fluid Exchange A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins. Capillaries are most abundant in tissues and organs that are metabolically active.apillaries are where fluids, gasses, nutrients, and wastes are exchanged between the blood and body tissues by diffusion. Capillary walls contain small pores that allow certain substances to pass into and out of the blood vessel.

Understanding Capillary Fluid Exchange Capillaries are where fluids, gasses, nutrients, and wastes are exchanged between the blood and body tissues by diffusion. Capillary walls contain small pores that allow certain substances to pass into and out of the blood vessel.hese structures are located between arterioles and capillaries and contain muscle fibers that allow them to contract. When the sphincters are open, blood flows freely to the capillary beds of body tissue. When the sphincters are closed, blood is not allowed to flow through the capillary beds.

Cardiovascular System Function Blood circulates through a network of vessels throughout the body to provide individual cells with oxygen and nutrients and helps dispose of metabolic wastes. The heart pumps the blood around the blood vessels. Functions of blood and circulation: 1  Circulates OXYGEN and removes Carbon Dioxide. 2  Provides cells with NUTRIENTS. 3  Removes the waste products of metabolism to the excretory organs for disposal. 4  Protects the body against disease and infection.

Functions of the Cardiovascular System With its complex pathways of veins, arteries, and capillaries, the cardiovascular system keeps life pumping through you. The heart, blood vessels, and blood help to transport vital nutrients throughout the body as well as remove metabolic waste. They also help to protect the body and regulate body temperature. The cardiovascular system consists of the heart, blood vessels, and blood. This system has three main functions: Transport of nutrients, oxygen, and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide, nitrogenous wastes).

Bright Hub Education The Circulatory System. Veins, arteries and capillaries are the three types of blood vessels in the circulatory system. The blood vessels carry blood, which contains antibodies, nutrients, oxygen, electrolytes and hormones, throughout the body to be used by the organs.f you laid out your blood vessels, including your arteries, veins and capillaries, in a long line, they would stretch out for about 60,000 miles long for a child and about 100,000 miles long for an adult.

- A 1:12 slope would require a ramp that is the same length as your rise. A 1:12 slope for a 12 inch rise would need a 12 foot ramp. One inch of rise means one foot of ramp. NOTE: Consideration must be taken if the ground is not level and slopes away from the rise where the ramp will be placed.

THE CIRCULATORY SYSTEM Veins are blood vessels that transport blood to the heart. With the exception of the pulmonary vein, they carry deoxygenated blood. They have three layers in their walls as well. The main difference is that there is less smooth muscle in the middle layer and less connective tissue in the outer layer.escribe the 4 functions of the cardiovascular system. 1. Contractions of the heart generate blood pressure which moves blood through the blood vessels. 2. Blood vessels transport blood from the heart to the arteries, capillaries, and veins. Blood then returns to the heart. 3. Gas exchange occurs in the capillaries.

How Your Circulatory System Works Blood flows continuously through the capillaries, it does not squirt and pause as your heart beats. This continuous flow is necessary because there is a constant exchange of oxygen and nutrients happening in the capillary walls. No cell in the body is far from a capillary.

Understanding Capillary Fluid Exchange Share. A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins. Capillaries are most abundant in tissues and organs that are metabolically active.apillary walls are thin and are composed of endothelium (a type of simple squamous epithelial tissue). Oxygen, carbon dioxide, nutrients, wastes, and fluids are exchanged through the thin walls of the capillaries. Once the blood leaves the capillaries it is returned to the heart via the veins.

Understanding Capillary Fluid Exchange On the venule end of the capillary bed, blood pressure in the vessel is less than the osmotic pressure of the blood in the vessel. The net result is that fluid, carbon dioxide and wastes are drawn from the body tissue into the capillary vessel. Blood Vessels. Arteries - transport blood away from the heart. Veins - transport blood to the heart. Capillary - transport blood from arteries to the veins. Sinusoids - vessels found in certain organs including the liver, spleen, and bone marrow.

Circulatory system All cells in the body need to have oxygen and nutrients, and they need their wastes removed. These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen.

What are the Different Types of Capillaries? The role of the capillary is to connect the arterioles and the venules. Arterioles are small blood vessels that branch out from arteries, while the venules branch out from veins. Arteries are the vessels that carry clean, nutrient-and oxygen-rich blood from the heart to the remainder of the body.
